I run Emacs on Mac OSX, I'm trying to switch from Emacs for Mac OSX to Emacs Mac Port.
I use notmuch for email. It works perfectly on Emacs for Mac OSX.
But on Emacs Mac Port, it's prohibitively slow. Also, the message list is messed up, double spaced and with strange boxes:
I'm using the exact same configuration as I do with Emacs for Mac OSX.
What's causing these problems, and how do I fix them?
